Windows Phone 7 cannot connect to m.google.com

q: We have a Windows Phone 7 that displays the message "we're having a problem connecting to m.google.com"
a: We discovered a couple of solutions for this.  The root cause appears to be the phone is not on wifi and is trying to use the Cellular data but fails.

1. From the phone, open Settings, open Cellular, open Data.
2. Make sure Data is on.  
3. If on, you might try to change it to off, then back on.
4. The most simple suggestion might be to simply power cycle the phone.

NOTE: What we know is that when Data is set off, the phone reliably generates this error message.
